The 20-year-old singer has admitted she once ''cried'' over a shoe that was thrown into the audience by band member Niall Horan at one of the 'History' hitmakers' shows in Miami.

Asked about her own experiences of being a fan and why she thinks that makes her relatable to her own fans, the former Fifth Harmony member said: ''I was a One Direction superfan, I even had my Twitter account dedicated to them.

Fifth Harmony ''did everything'' in their power to make the band work after Camila Cabello's exit.

The future of the group - comprised now of Normani Kordei, Lauren Jauregui, Ally Brooke and Dinah Jane Hansen - was thrown up into the air last year when the 20-year-old singer announced she was leaving them in order to release solo material, but they have admitted there was no chance they were going to let things fall apart because of one member's departure.

Normani said: ''I get to sleep at night knowing we did everything in our power as friends, bandmates and human beings (to make it work).''
